Abstract :
The authors propose a novel microstrip antenna which has broad bandwidth and small size. An excellent example of this microstrip antenna, a slender base station antenna, is shown. The double-layered broadband microstrip configuration yields a bandwidth of 17% at a voltage standing wave ratio of 1.5. The antenna width is extremely small at about 40 mm. The 120 degrees beamwidth in the horizontal plane is achieved by employing a 100-mm-width ground plane. A slender base station antenna covered with a 160-mm-diameter cylindrical radome has been constructed and tested. The measured radiation characteristics are satisfactory.<>
